therefore be supplied to the intake manifold,

or in other words more fuel will be delivered 5 to the engine cylinderin the subsequent operation of the engine. lIn such instances, the heavyfuel may accumulate in the lower end of the jacket on the casting 19,and when the engine is not in operation clog the outletinto the pipe 35,or in the operation of the engine pass into the cylinders in a liquidstate. I therefore provide the drain port indicated at 36 at the lowestpoint of the chamber 3() so that such unvaporized fuel V may readilyfind an outlet.

lirom the foregoing description taken in connection with theaccompanying drawings, the construction, manner of operation and severaladvantages of my invention will be readily understood. By means of thedevice, l am enabled to use kerosene and other low grade fuels for motorvehicle engines with highly satisfactory results. By the operation ofthe exhaust control valves 25 and 26 in unison with the throttle valve,a

preheating of the kerosene and air to the proper degree for its finalvaporization by the heat of the compression in the engine cylinder, isassured and as air is mixed with the kerosene fuel prior to the heatingthereof as well .is subsequently, the danger of an over-rich mixturebeing drawn into the engine cylinder is obviated. It will therefore beseen that appreciable economy may be 85 reailized in the operation ofmotor vehicle engines by means of the present invention. The valve 17may be regulated to control the amount of auxiliary air passing into themixing chamber formed by the connection u and thus the richness of themixture may be readily controlled or cold air may he admitted to therebyprevent the tem- "perature of the mixture, when admitted to the engine,being, too high. Furthermore,

this valve 17 will,y to a considerable extent,

control the suction through the inlet tube 33 and downward through thevaporizing chamber 30 and through the pipe 35. It will bc noted that thepipe 35 is downwardly inclined so that any condensed gas or vapor whichmay coll-ect in the pipe 33 will run down this pipe and be dischargedinto the lower cud of theebamber 30 and tbu.-: be discharged through thedrainage 'l`hc device readily lends itself to usc in connection withvarious types of fuel carburetor-s and the invention is accordingly not.to be limited to the Heat controlled fuel supply means which l havelli-rein referred to and illustrated in the ac;

companying drawings. The device is likewisc susceptible of many othermodificalions in the proportion and relative arrangement of its severalparts, and l therefore reserve the privilege oiA adopting all Such' by.the

'lene or like highly volatile fuel, or to a source of kerosene or likelow grade fuel, and that I'have provided means whereby the low 'radefuel may be vuporized either eat of the cylinders themselves when theengine has been running for some time, or by the heat of the exhaustwhen the engine is initially started, and provide means whereby thissecond named source of heat is automatically reduced or cut off entirelyin correspondence with the opening of the throttle valve so as toprevent the mixture from being too hi hly heated when it enters thecylinders an thus preventing all chances of pre-ignition or unduecarbonization of the fuel within the cylinders. It will further he seenthat I have provided means whercbvaair to a. proper and regulat'ableamount may be admitted and mixed with the gasolene or highly volatilefuel, or mixed to a greater or'less amount with the vaporized mixture offuel and primar air coming from the carbnreting and pre eatin r chamber.
